“…Currently, theoretically substantiated and tested in practice, the methods of the Markov theory of optimal filtration. This theory has been fully and strictly developed in a number of books and articles [1][2][3][4][5][6][7][8][9][10][11][12]. In [6,10,11], the solution to the problem of adaptive filtering of signals based on the use of the lemma on the inversion of the correlation matrix (MIL) of input signals of an adaptive filter is considered.…”

Many tasks of digital signal processing require the implementation of matrix operations in real time. These are operations of matrix inversion or solving systems of linear algebraic or dif- ferential equations (Kalman filter). The transition to the implementation of digital signal processing on programmable logic device (FPGAs), as a rule, involves calculations based on the representation of numbers with a fixed point. This makes solving spatio-temporal processing problems practically im- possible based on conventional computational methods. The article discusses the implementation of spatial-temporal signal processing algorithms in satellite broadband systems using QR decomposition. The technologies of CORDIC computations required for recurrent QR decomposition when used together in systolic algorithms are presented

Remote sensing of the Earth is mainly carried out in the visible region of the spectrum, which corresponds to the current level of development of high-precision onboard instruments for Earth remote sensing. At the same time, methods and equipment for sensing in the radio- and infrared ranges of the electromagnetic spectrum are widely used and developed at a faster pace. The frequency of data acquisition ranges from once per month to once per minute, the spatial resolution ranges from kilometer to centimeter scales, and the electromagnetic spectrum covers wavebands ranging from visible light to microwave wavelengths. The efficiency of Earth remote sensing information delivery to consumers is considered under different variants of satellite-repeater network construction, taking into account the characteristics of existing and prospective high-speed radio lines of spacecrafts.

The article discusses issues in the research and trial operation of satellite communications systems in the following operating modes: “satellite - earth”, “earth - earth”. The results of this study will serve as the fundamental basis for creating new promising technical solutions, using which it is possible to create and modernize both classical and quantum multifunctional ground-based systems and on-board radio-technical and optical communication systems.
